In this episode

Come hang out with Joe Beda as he does a bit of hands on exploration of Kubernetes and related topics. Some of this will be Joe talking about the things he knows well. Some of this will be Joe exploring something new with the audience. Ask questions, comment and help decide where things go.

This week we will be exploring monitoring with Prometheus. Joe hasn't used Prometheus before (but has used similar systems inside of Google). We'll install it and try to get some simple metrics connected. Let's see how far we can get in ~1.5 hours.
